[hibernate-dev] Migration path from 3.6 to 5.2

Hi, We have been using hibernate-orm in our application for a long time. The version of hibernate we use is 3.6.10.Final. I know it is archaic. We would like to migrate to the latest stable version (5.2) to reap the benefits of new optimizations and features. Initially we thought about upgrading to 4.x. Since we are also doing Java 8 and Spring 4 upgrades, we have decided that it would be better to migrate hibernate to 5.2 together. I know it is not possible to migrate from 3.6 to 5.2 directly.I have checked online for migration guides. But I am bit off about which path should I take to migrate (eg. 3.6 to 4.3 to 4.5 to 5.2). Can someone help me with figuring out minimum number of migrations from 3.6 to reach 5.2? I would be grateful if you could point me to some resources
